1. A psychological disorder is said to have an acute onset if the symptoms develop ______, while it has an insidious onset if the symptoms develop ______.

• A. Suddenly;gradually
• B. Suddenly;atypically
• C. Gradually;atypically
• D. Atypically;suddenly

Correct answer: A

Rationale: An acute onset refers to the sudden development of symptoms, whereas an insidious onset indicates a gradual progression of symptoms. Therefore, the correct answer is 'Suddenly;gradually.' The other choices are incorrect because 'atypically' does not accurately describe the onset of symptoms in this context.

2. Scientific research has demonstrated the __________ parenting style is most likely to lead to healthy psychological development in children.

• A. Authoritarian
• B. Permissive
• C. Authoritative
• D. Neglectful

Correct answer: C

Rationale: Scientific research has demonstrated that the authoritative parenting style is most likely to lead to healthy psychological development in children. Authoritative parents are responsive to their children's emotional needs, set clear boundaries, and encourage independence. This balance fosters a positive environment for children to thrive emotionally and psychologically. Authoritarian parenting (choice A) focuses on strict rules without much warmth, which can lead to obedience but may hinder emotional development. Permissive parenting (choice B) lacks structure and rules, potentially resulting in children feeling insecure. Neglectful parenting (choice D) is characterized by a lack of responsiveness and involvement, leading to various negative outcomes for the child's development.

3. Why is it particularly useful to study identical twins who were raised in different environments?

• A. Differences in brain function can be easily identified.
• B. Concordance rates tend to be higher.
• C. It is possible that the genetics of twins who have been separated have changed in ways to explain any differences found.
• D. It is possible that high concordance rates between identical twins reared together are due to their being treated more similarly than nonidentical twins.

Correct answer: D

Rationale: Studying identical twins raised in different environments allows researchers to understand the impact of genetics versus environmental factors on traits. Choice A is incorrect because differences in brain function can be influenced by a variety of factors and not solely by environmental differences. Choice B is incorrect as concordance rates tend to be higher in identical twins reared together due to shared genetics and environment. Choice C is incorrect because genetics do not change due to being raised in different environments.

4. What are genes made of?

• A. Trisomes
• B. Chromosomes
• C. DNA
• D. Proteins

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

5. What research method involves researchers using interviews and/or questionnaires to collect data about attitudes, interests, values, and various kinds of behaviors?

• A. Case study
• B. Survey
• C. Naturalistic observation
• D. Correlational study

Correct answer: B

Rationale: The correct answer is B: Survey. A survey is a research method where data is collected through interviews or questionnaires about various behaviors and attitudes. In a case study (choice A), researchers closely examine a particular individual or group. Naturalistic observation (choice C) involves observing subjects in their natural environment. Correlational study (choice D) examines the relationship between two variables but does not involve collecting data through interviews or questionnaires.
